Calculate `log_(10){[C]_(eq)//[A]_(eq)}` where [C] and [A] are equilirium molar concetration of respective species, when 2 2 mole each of A and B were allowed to come to equilibrium at 900 K. `A + B overset(900 K) hArrC + D" ", " "DeltaG^(@) = 460.6 "Calorie"` Take: `underset(R=2 Cal //K"mole")(ln X = 2.303 log X)`A. `5.56 xx 10^(-02)`B. `5.57 xx 10^(-03)`C. `1.1 xx 10^(-2)`D. `1.1 xx 10^(-3)` |

Answer» Correct Answer - A `DeltaG^(@)= 2.303 RT log K_(C)` `460.6 = - 2.303 xx 2 xx 900 log K_(C)` `log K_(C) = -(1)/(9)` `log .([C]_(eq)^(2))/([A]_(eq)^(2))=(1)/(9)" "log.([C]_(eq))/([A]_(eq)) = -(1)/(18) = 5.56 xx 10 ^(2) " "("at equilibrium "[C]_(eq) = [D]_(eq)[A]_(eq)=[B]_(eq))` |
